1 point Two forces F1 = 2.6i + (-4.5)j N and F2 = (-6.0)i + (-1.3)j N are presented in Cartesian vector form (i acts left to right, j acts vertically upward). What is the angle, measured in degrees anticlockwise from the i direction, of the resultant force of F1 and F2? Type your answer.. 2 points For the horizontal beam of length 2m with applied loads as shown in the figure, the moment about the point A (taken with counter-clockwise as being positive) is known to be zero. What is the magnitude of the two forces marked a. Assume negligible thickness of the beam. Give your answer in Newtons (N). b= 20.4 N, c= 1.1m bN 0.5 m ON 45 5 Nm A cm 0.5 m ON5 2 points It is required to move the 54 kg crate from its present position shown in the diagram, to its new position where it is directly above the trailer. What is the magnitude of the horizontal force P (in Newtons) the worker must exert to achieve this? (take g = 9.81 ms-2). a = 1.08 m 2 1 Type your answer.
